IMPROVEMENT iN APPARATUS FOR TRIMMING HEELS OF BOOTS AND SHOES.

The Schedule referred to in these Letters Patent and making pa'xt of the lame.

`Toall whom it may concern.- v

Be it known that I, Louis CoT, of St. Hyacinth city and county, Province of Quebec, in Canada, have invented au Improved Hand Apparatus for Trim-t ming .Heels of Bootsand Shoes; and I dohereby declare that the following, taken in'couuection with the drawings which accompany and form part 'of this specification, is a description of my invention suiii-4 cient to enable those skilled in the art to practice it.

This ,apparattus is designed for use by hand' with `the boot and shoe-holding machine shown and described in the. United States Letters Patent No. 104,560, grantedtp me June 21, 1870, on with any suitable apparat-us, which, while it holds'a'boot or shoe firmly, is' provided with'a center-pin to which to connect my trimming apparatus, so that it can be moved around the convex outline of a. heel,and a guide-plate located on vthe heel-tread to supply one of the' two guides needed, the other guide being found on the .counter of the shoe itself.

In the drawings- Figure 1 shows in full lilies a side vie'iv of my i1u.

proved apparatus, and

Figure 2 shows in full lines a plan of the sam,e,both4 as applied in the act of trimming a heel.

The dotted lines shown in said guresrepreseut parts of a hoot or shoe to be operated upon, the guide.- plate It upon the tread of the heel, and the piece j, which receives the guideeplate, and is provided with the pivot or center, about: which my apparatus is cai ried.

4The lever c is the piece towhich a workman applies inost of the force necessary to vmake Athe knife perform its function of cutting.

At one end of said level' an eye or socket is made to fit upon the pivot-pin b, the other end of the lever being supplied with a suitable handle, c`

To the lever a is pivoted, at d, the lever e, having' one end connected to the handle c by a spring, f, the other end of lever eheing kept forced, by the spring f, against the radius-arm g, which has a pivot-hole, which receives one 4end of the knife-carrier, one end of which passes through said hole, and has ,se- 'cured between said arm g and a-nut, It, on the end of the knife-carrier, a spring, i, which admits of endwise movement of the knife..

The other end of the ,knife-carrier, whicn is extended soine distance from the knife-for convenience,

is provided with a cross-handle, l, .by which the operator keeps Jthe edge of the knife at a propeeangle to the path of its movement, the apparatus requiring in use the application ofboth hands of the workman.

'ilhe knife-blade m, in practice, is adj ustably andremovably attached to the carrier urso that it may be readily removed for sharpening, and'suitably fixed in position.

The carrier' n has connected with it a guard and gauge, o, arranged so that its location may he changed by-manipula'tion of. screw p, which passes ,throughA a slot in the carrier n.

The back of this piece crests against the counter g, and thefend edge of o bears against the sole r, on that surface nearest the counter, the yielding of springt compensating for any variation of height of the heel from front to rear, andvkeepiugthe end edge of guard ein close contact with the sole r.

The end of the'knife or of .the knife-carrier nearthe 'radiusarrn g` is kept pressed against the heel-tread k by the action of spring f, Awhich yields enoughlto compensate for the varyingdistances'which the knife is obliged -to take from the heel centeri'n passing around The other partf the knife is kept in place, an'd the back of guard o pressed against the counter, byforce applied .to the handle l.

From the foregoing it will be seen'how a workman can rapidly and perfectly shave smoothly a rough heel attached to a lasted booter shoe, by making use. of the described apparatus in connection 'withv any device or apparatnsor machine which 'presents a pivot or center for the lever a, a tread guide-plate, k, and

means for-holding the lasted boot or shoe in position,

one continued movement 'and one cut around the heel effecting the object of reducing the rough heel to the desired shape and size, the counter being atthe same time protected from risk ofheing cut bythe knife.

To vary the tension of the spring f, I prefer, in

practice, to connect one end thereof izo-handle c by means of a 'clamp-screw adjustable in a slot cutthrough the handle.

For heels of various heights, the guide and guard o is adjusted on the knife-carrier n, so as to cover more or less of the edge of the knife.

I claim- A handfoperated heeltrimming tool, constructed as described.
